摘要
针对邢东矿2222工作面回采中遇到的片帮难治理的问题,通过现场观测,得到了大倾角大采高仰采工作面煤壁的片帮特点,同时通过分析其片帮的机理,提出减缓煤壁承受压力、提高煤体强度是片帮治理的主要途径。通过采取煤壁注浆以及工作面支架改造等方式实现了2222工作面的顺利回采,可为类似条件下的工作面回采提供借鉴。
In order to solve the problem in mining of Face No.2222, the spalling characteristics of large mining height rise mining face with large inclined angle were obtained by way of field observations. On the basis of the analysis of the mechanism for rib spalling, the treatment method of decreasing the coalwall pressure and increasing the strength of the coal wall were put forward. At last the means of coal wall grouting, the support reformation and so on, the Face No.2222 was successfully recovered, which can provide reference for mining under similar conditions.
